Background Hysterectomy for benign indications has been associated with an increased risk for lower-urinary-tract sequela, but results have been inconclusive. We aimed to establish the risk for stress-urinary-incontinence surgery after hysterectomy for benign indications. Methods We did a nationwide, population-based, cohort study from 1973 to 2003 in Sweden. We identified our population from the Swedish Inpatient Registry. We selected 165 260 women who had undergone hysterectomy (exposed cohort) and a control group of 479 506 individuals who had not had this procedure (unexposed cohort), matched by year of birth and county of residence. In both cohorts, occurrence of stress-urinary-incontinence surgery was established from the Swedish Inpatient Registry. Hazard ratios with 95% CIs were calculated by Cox's proportional-hazards regression. Findings During the 30-year observational period, the rate of stress-urinary-incontinence surgery per 100 000 person-years was 179 (95% CI 173–186) in the exposed cohort versus 76 (73–79) in the unexposed cohort. Correspondingly, individuals in the exposed cohort were at increased risk for stress-urinary-incontinence surgery compared with those in the unexposed cohort (hazard ratio 2·4; 95% CI 2·3–2·5), irrespective of surgical technique. Risk for stress-urinary-incontinence surgery varied slightly with time of follow-up: the highest overall risk was recorded within 5 years of surgery (2·7; 2·5–2·9) and the lowest risk was seen after an observation period of 10 years or more (2·1, 1·9–2·2). Interpretation Hysterectomy for benign indications, irrespective of surgical technique, increases the risk for subsequent stress-urinary-incontinence surgery. Women should be counselled on associated risks related to hysterectomy, and other treatment options should be considered before surgery.
